I'm using the explicit rule and marking these targets not to be 
built by default, with the intent to avoid disturbing the whole 
(default) build process. 

But when I'm building (sub)projects in my main project jamfile via 
the build-project rule, all targets, including explicit gets built. 

Is this an intentional behavior or a bug? 
If not a bug, is there some other way to build only implicit targets 
in the subprojects? 
Or maybe some compleatly different approach to exclude some targets 
from the overall default build? 

I expected that build-project rule will behave the same way as 
invoking bjam with no target in the corresponding project's 
directory ... 

I'm using: 
Boost.Build V2 (Milestone 10) 
Boost.Jam 03.01.10
